Each time a users visits my web site pages, several xml elements are written and removed from one predefined file.
每次用户访问我的网站页面时，都会从一个预定义文件中写入并删除多个xml元素。
Eventually there will be a situation, when on this same file a read and write operation will take place almost simultaniously. How do I handle concurrency in this case? Is there a special base class library class that can handle it for me?
最终会出现这种情况，当在同一个文件上时，读写操作几乎同时发生。在这种情况下如何处理并发？是否有一个特殊的基类库类可以为我处理它？

XML files will not do this for you. You could set up a synchronizing object: the simplest would be to have a common function that accesses the file and use the lock key word. Use a Mutex for inter-process synchronization.
XML文件不会为您执行此操作。您可以设置同步对象：最简单的方法是使用一个访问文件并使用锁定关键字的公共函数。使用Mutex进行进程间同步。
However, this will be a potential bottle neck.
然而，这将是一个潜在的瓶颈。
It may be time to start using a database.
可能是开始使用数据库的时候了。
